Dual use of wifi and ethernet with official android os

VIM1S Android
1

Which version of system do you use? Khadas official images, self built images, or others?

khadas official android

Please describe your issue below:

It’s seems that android until version 11 does not allow dual use of more than one network interface, But, since i use the official image, i was wondering if Khadas has solved this issue somehow?

My need does not involve internet. My VIM1s connect to an AP without internet and when i tried to connect to VIM1s from my PC through ethernet the applications using WIFI sees NO WIFI.

Some threads on internet speaks about modification of ConnectivityService.java in the android framework but they are quite old and hence led me to think that may be such old problem were already solved by Khadas.
